Ah - you must have missed (or forgotten) this quote. The important part is at about 9:20 - this link will start you out at 8:43. Bonus - the "lemons" quote starts at about 10:20.http://www.youtube.com/watch?v=i8glYx2qQx4&t=8m43s

I just finished Chapter 2 last night and while I do like the mechanics and innovative puzzle solving needed, and of course the vocals absolutely crack me up, it hasn't "grabbed" me yet. I mean I am enjoying it but I'm not overwhelmed with it (yet). Of course it is still pretty early in the game...

Don't worry, you're not alone in that regard. I was moving at a snail's pace through Portal 2 in the first few chapters over several days playing it in short bursts. The game really takes off later on and I ended up getting hooked at a certain point enough to see it through completion without stopping.
